For Exceptionhandling, I want to know, which getter/field in a given Bean produced the Exception. What I do not want is a try/catch around every getter-call, or having to manually keeping track with a String variable.
Can I use Java Reflections for it? How could I design an Interface the Bean implements?
Pseudo-Code where I want the Exception handling to happen:
try {
step.setNo(Long.parseLong(stepElement.getChildText("no", nameSpace)));
step.setName(stepElement.getChildText("name", nameSpace));
step.setDetail(stepElement.getChildText("detail", nameSpace));
step.setEcuName(stepElement.getChildText("ecu-name", nameSpace));
}catch(Exception e){
String fieldname = /*which field did throw? */
}
Part of the actual Bean:
public class CupProcStep {
private long no;
private String name;
private String detail;
private String ecuName;
private String ecuVariant;
private String diagnosticsId;
private String errorText;
private String stepResult;
public long getNo() {
return no;
}
public void setNo(long no) {
this.no = no;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDetail() {
return detail;
}
public void setDetail(String detail) {
this.detail = detail;
}
public String getEcuName() {
return ecuName;
}
The name of the field, that threw the Exception, e.g. "no","name,"ecuName", etc.
